Your Škoda dealer can also supply you with the correct coolant additives.
Caution
•
Other coolant additives may cause operational problems which,
in particular, involves significantly reducing the anticorrosion effect.
•
Any faults or problems resulting from corrosion may cause a loss
of coolant and, as a consequence of this, result in major engine
damage.
Inspecting the coolant level
The coolant expansion bottle is located in the engine compart-
ment on the left.
– Switch the engine off.
Using the system Safety
– Open the bonnet ⇒
– Check the level of coolant in the coolant expansion bottle
If the coolant level in the reservoir is too low, this is indicated by the
warning light in the instrument cluster
recommend inspecting the coolant level directly at the reservoir from time
to time.
Loss of coolant
A loss of coolant is first and foremost an indication of a leak in the
system. You should not merely top up the coolant in the reservoir. It is also
important to have the cooling system inspected without delay by a
specialist garage.
Losses can only occur through the pressure relief in the cap of the coolant
expansion bottle which is completely free of leaks if the coolant boils as a
result of overheating and is forced out of the cooling system.

One should contact a specialist garage as soon as possible if the source
of overheating itself cannot be determined and removed, since there may
be grave damage to the engine.
